  1. 1. INTRODUCTION TO PHOTOGRAPHY
  2. 2. What Is Photography?The process and art of creating still picturesDerived from the Greek words Photos (light) and Graphis(painting/drawing).Technique and art of painting or drawing with light.
  3. 3. How Is A Photograph Taken?Image is recorded on a light sensitive material (digital sensor).Various parts of camera help to control the amount of lighthitting the material.These are: 1. Aperture 2. Shutter Curtain (controls the shutter speed) 3. ISO setting
  4. 4. Common TermsExposure - The act of taking a photograph by exposing the sensor to lightAperture - A hole found in the lens that controls the amount of light thelens to hit the sensor. Bigger hole = more light entering the camera.Denoted by f/numberShutter Speed - The speed a shutter “curtain” opens and closes to controlamount of time the “curtain” remains open to allow light in. Longer shutterspeed = more light entering the camera. Denoted by 1/numberISO - Sensitivity of sensor to light. Higher ISO = more sensitive to light.Usually denoted by numbers from 100, doubling at each stop (e.g. 100,200, 400, 800 etc)Subject - The “hero” of your photograph. The person/object you are takinga photograph of.
  5. 5. Common TermsFocal length - Focal length refers to the distance between thephotographer and her subject. It is also the number found on your lens, inmm.Composition - The art and science of placing elements within aphotograph to “tell a story” to the viewer.Aperture Priority mode - User sets aperture, camera then selects amatching shutter speed to ensure correct exposure.Shutter Priority mode - User sets shutter speed, camera selectsa matching aperture to ensure correct exposure.Manual mode - User selects both shutter speed & aperture to ensurecorrect exposure
  6. 6. Parts of a DSLR
  7. 7. Focal LengthNumbered in mm on the camera lens.Angle of view of your camera and how close the subject ofyour photograph appears to the viewer.Range of numbers, e.g. 18mm - 55mm means lens covers18mm to 55mm focal lengthA lens with only 1 focal length is a prime lens while a rangeof focal lengths on the lens means it is a zoom lens
  8. 8. Focal Length Field of View
  9. 9. Focal Length Comparison
  10. 10. Types of Camera LensesUltra wide angle - A lens with focal length that is less than 24mmWide angle - A lens with focal length between 25mm to 35mmNormal/Standard - A lens with focal length of 50mm. It is called as suchbecause the field of view of a 50mm is the same as that of a human eye.Telephoto - A lens with a focal length from about 70mm to 300mmSuper Telephoto - A lens that has a focal length of more than 300mm
  11. 11. Lens - Prime or Zoom?Prime lens:Usually extremely high qualityBig maximum aperture (e.g. f/1.8)Most prime lenses are expensiveNeeds different lenses to cover a range of focal lengthsZoom lens:Usually not as high qualityUsually a range of maximum aperture (e.g. f/4 - f/5.6)*Most zoom lenses are reasonably pricedDoes not need a large number of lenses to cover a range of focallengths*This means the lens has a maximum aperture of f/4 at 18mm and a maximumaperture of f/5.6 at 55mm for an 18-55mm zoom lens.
  12. 12. How does a camera work? Image reflected off mirrors & pentaprism onto viewfinder through the lens Mirror lifts up to allow light to hit the digital sensor
